When using WDS bridging router, the system shows that the bridging is successful, but the Internet cannot access the Internet normally. In most cases, it is related to the settings of the primary and secondary routers.
The same channel is not selected
While most routers will synchronize their own channels with the main router when WDS bridging, there are still a few routers that need to be set up manually.
Therefore, when two routers show that the bridge is successfully connected but cannot access the Internet, you should first check whether the channels are the same. Routers on different channels cannot communicate with each other even if the bridge is successful.
IP address not changed
The secondary router is the wireless router used to enable the WDS function. It has the same functions as the main router and has an independent IP address.
Most operators will ignore the IP address of the secondary router. The secondary router application that is successfully bridged has the IP address of the same network segment as the primary router and cannot conflict with other devices.
For example, if the IP address of the primary router is 192.168.3.1 and the DHCP address pool is
192.168.3.100-192.168.3.200, then after the secondary router is successfully bridged, the LAN port IP address of the secondary router should be manually changed to 192.168. 3.X.
When setting, the IP address of the secondary router cannot be a gateway, and the value of X should be outside the DHCP address pool. For example, the IP address of the secondary router can be set to 192.168.3.254.
DHCP is not turned off
Except that the IP address of the secondary router cannot conflict with the settings in the primary router network, the secondary router as a transit device cannot enable the DHCP service.
DHCP, Dynamic Host Configuration Protocol. This service is responsible for allocating valid IP addresses to devices connected to the network and providing gateway, DNS and other services.
In the same network, if there are two DHCP servers, the device connected to the network later will not be able to obtain a valid IP address.
Therefore, when the WDS bridge is successfully connected and the LAN address is set for the secondary router, the DHCP service of the secondary router should be turned off to restore the Internet access function.
After we use one or several wifi for a long time, the computer will automatically connect every time it detects a wifi signal. When we change the password, the computer will not prompt for an incorrect password after connecting to wifi, nor will it pop up to enter the password. The window will only show that it cannot connect. What should we do at this time?
Start the computer, select "Network" on the desktop, then right-click the mouse and select "Properties"
In the properties window, select "Manage Wireless Networks" You can clearly see that there are many wireless networks saved. Now we select our Right-click the wireless network that changed the password and select "Delete Network"
After deleting the network, now we have to click on the wireless icon in the lower right corner of the computer, select the wireless signal for which you have changed the password, click Connect, and now you will be prompted Enter your password!
1. Use IE to log in to the routing settings page. The default should be 192.168.1.1. The default account is admin and the password is admin (usually this is the case).
2. Follow the wizard’s prompts to set it up again correctly. If the network gateway of the routing chain does not exist To enable the DHCP service, select a static address. If it is enabled, select automatic acquisition. If it is a static address, you need to enter the correct DNS address to access the Internet normally (pay attention to check this item).
3. Check if there are any problems with other routing settings.
4 .If you want to manually configure the local IP, turn off the DHCP service of the router and set the IP address manually. Note: The DNS address of the manually set IP must be the same as the DNS obtained or set by the router, otherwise the web page cannot be opened. 5. If the router is turned on DHCP service, then the local only needs to be set to automatically obtain an IP.
